Seventy-nine-year-old Martha Andersson dreams of escaping the dull, drab life of the retirement home. With no intention of spending the rest of her days confined to an armchair, she enlists her four oldest friends—a.k.a. the League of Pensioners—to rebel against the rules imposed upon them. Together, they cause an uproar with their antics: protesting against early bedtimes, tasteless meals, and a host of unfair cost-cutting measures. As the elderly friends become more daring, their activities escalate, and they devise a cunning plan to rob a bank in order to fund their exciting new lives. Determined to stand up for senior citizens everywhere—and not to be slowed down by their walkers—they outrun both the law and the lawless on their way to wealth and infamy.
